DESIGN PARAMETERS AND OPERATION CHARACTERISTICS OF BALL-TYPE SAFETY-OVERRUNNING CLUTCH WITH MODIFIED GROOVES
Bibliographic record
Abstract
The article investigates the force interaction of the elements and operation characteristics of a ball-type safety-overrunning clutch with modified semi-clutch grooves. Grooves modification provided through grooves sides to the semi-couplings radius inclination. Through balls with other clutch parts force interaction consideration, taking into account inertia and friction forces, obtained expressions for calculating of clutch parts loadings, main moments of the clutch: rating, operation beginning and ending. Those make possibility to evaluate main clutch operation characteristics - coefficients of accuracy, sensitivity, and rating torque exceeding. Influence of main design parameters on clutch operation characteristics is studied. Particularly it is shown that grooves to clutch axe inclination angle exerts a great influence on parts load and clutch operation characteristics in overload mode. It is shown that in highly loaded high-speed drives it is advisable to install clutches with inclined to the radius grooves sides. It is shown that from the point of view of increasing clutch operation characteristics, it is more advantageous to make the grooves at smaller angles to the clutch axe. It is established that characteristics of clutch with inclined to the radius grooves sides are not very sensitive to changes in operation rotating frequency. Reducing the balls diameter makes a positive effect on the clutch operation characteristics in overload mode through inertia and friction forces impact decreasing and reducing contact stresses in balls with grooves contact zone. Practically significant ratios for the design and verification calculations of presented clutch parts loads and stresses are obtained. Presented results are useful for engineers dealing with mechanical driving design. Keywords: clutch, torque, overload, gearing, stress, operation accuracy, contact strength, operation characteristics

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
